在普通的java类中获得spring上下文

 package org.company.xxx;
 
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
/**
 * 获取spring容器，以访问容器中定义的其他bean
 */
public class SpringContextUtil implements ApplicationContextAware {
 
	// Spring应用上下文环境
	private static ApplicationContext applicationContext;
 
	/**
	 * 实现ApplicationContextAware接口的回调方法，设置上下文环境
	 */
	public void setApplicationContext(ApplicationContext applicationContext)throws BeansException  {
		SpringContextUtil.applicationContext = applicationContext;
	}
 
	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}
 
	/**
	 * 获取对象
	 * 这里重写了bean方法，起主要作用
	 * @param name
	 * @return Object 一个以所给名字注册的bean的实例
	 * @throws BeansException
	 */
	public static Object getBean(String beanId) throws BeansException {
		return applicationContext.getBean(beanId);
	}
}

 Bean配置:

<bean id="SpringContextUtil" class="org.company.xxx.SpringContextUtil" />

  实现了ApplicationContextAware接口，在Bean的实例化时会自动调用setApplicationContext()方法!
